Lecture Templates: Convenient Partial Lecture Delivery SystemElzbieta Cook and Robert L. CookReports on the use of two forms of PowerPoint lecture presentationsa complete version used by the lecturer and a corresponding partial version available in advance to students. Pre-prepared lecture presentations allow for the sharing of lecture materials among teaching faculty and ensure consistency among several lecture sections in team taught courses.Cook, Elzbieta; Cook, Robert L. J. Chem. Educ.2006, 83, 1176.

How We Teach Molecular Structure to FreshmenMichael O. HurstExamination of how textbooks discuss various aspects of molecular structure; conclusion that much of general chemistry is taught the way it is for historical and not pedagogical reasons.Hurst, Michael O. J. Chem. Educ.2002, 79, 763.

Lewis Structures in General Chemistry: Agreement between Electron Density Calculations and Lewis StructuresGordon H. PurserThe internuclear electron densities of a series of X-O bonds (where X = P, S, or Cl) are calculated using quantum mechanics and compared to Lewis structures for which the formal charges have been minimized; a direct relationship is found between the internuclear electron density and the bond order predicted from Lewis structures in which formal charges are minimized.Purser, Gordon H. J. Chem. Educ.2001, 78, 981.

Lewis Structures Are Models for Predicting Molecular Structure, Not Electronic StructureGordon H. PurserThis article argues against a close relationship between Lewis dot structures and electron structure obtained from quantum mechanical calculations. Lewis structures are a powerful tool for structure prediction, though they are classical models of bonding and do not predict electronic structure. Purser, Gordon H. J. Chem. Educ.1999, 76, 1013.
